If you deny the Big Bang, how do explain the redhift of the galaxies?
How do explain the CMB? How do you explain the isotropy of the CMB to
1 part in 10^5? The evidence for the Big Bang is beyond overwhelming.

A separate question is whether the Universe existed for an infinite
length of time. Within the inflationary model, you could have eternal
inflation. So the irony is that inflation, which saved the Big Bang
model, could ultimately allow the possibility that the Universe could
have existed for an infinite length of time after all.
